A company is migrating an application to AWS.It wants to use fully managed services as much as possible during the migration.The company needs to store large, important documents within the application with the following requirements:✑ The data must be highly durable and available.✑ The data must always be encrypted at rest and in transit.✑ The encryption key must be managed by the company and rotated periodically.Which of the following solutions should the Solutions Architect recommend?Read More →

A company has a legacy application running on servers on premises.To increase the application’s reliability, the company wants to gain actionable insights using application logs.A Solutions Architect has been given following requirements for the solution:✑ Aggregate logs using AWS.✑ Automate log analysis for errors.✑ Notify the Operations team when errors go beyond a specified threshold.What solution meets the requirements?Read More →

An auction website enables users to bid on collectible items.The auction rules require that each bid is processed only once and in the order it was received.The current implementation is based on a fleet of Amazon EC2 web servers that write bid records into Amazon Kinesis Data Streams.A single t2.large instance has a cron job that runs the bid processor, which reads incoming bids from Kinesis Data Streams and processes each bid.The auction site is growing in popularity, but users are complaining that some bids are not registering.Troubleshooting indicates that the bid processor is too slow during peak demand hours, sometimes crashes while processing, and occasionally loses track of which records is being processed.What changes should make the bid processing more reliable?Read More →

A Solutions Architect is designing a system that will collect and store data from 2,000 internet-connected sensors.Each sensor produces 1 KB of data every second.The data must be available for analysis within a few seconds of it being sent to the system and stored for analysis indefinitely.Which is the MOST cost-effective solution for collecting and storing the data?Read More →

A company receives clickstream data files to Amazon S3 every five minutes.A Python script runs as a cron job once a day on an Amazon EC2 instance to process each file and load it into a database hosted on Amazon RDS.The cron job takes 15 to 30 minutes to process 24 hours of data.The data consumers ask for the data be available as soon as possible.Which solution would accomplish the desired outcome?Read More →

A company runs its containerized batch jobs on Amazon ECS.The jobs are scheduled by submitting a container image, a task definition, and the relevant data to an Amazon S3 bucket.Container images may be unique per job.Running the jobs as quickly as possible is of utmost importance, so submitting job artifacts to theS3 bucket triggers the job to run immediately.Sometimes there may be no jobs running at all.However, jobs of any size can be submitted with no prior warning to the IT Operations team.Job definitions include CPU and memory resource requirements.What solution will allow the batch jobs to complete as quickly as possible after being scheduled?Read More →

A company used Amazon EC2 instances to deploy a web fleet to host a blog site.The EC2 instances are behind an Application Load Balancer (ALB) and are configured in an Auto Scaling group.The web application stores all blog content on an Amazon EFS volume.The company recently added a feature for bloggers to add video to their posts, attracting 10 times the previous user traffic.At peak times of day, users report buffering and timeout issues while attempting to reach the site or watch videos.Which is the MOST cost-efficient and scalable deployment that will resolve the issues for users?Read More →

A company is planning to migrate an application from on-premises to AWS.The application currently uses an Oracle database and the company can tolerate a brief downtime of 1 hour when performing the switch to the new infrastructure.As part of the migration, the database engine will be changed to MySQL.ASolutions Architect needs to determine which AWS services can be used to perform the migration while minimizing the amount of work and time required.Which of the following will meet the requirements?Read More →

A company is running an application on several Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer.The load on the application varies throughout the day, and EC2 instances are scaled in and out on a regular basis.Log files from the EC2 instances are copied to a centralAmazon S3 bucket every 15 minutes.The security team discovers that log files are missing from some of the terminated EC2 instances.Which set of actions will ensure that log files are copied to the central S3 bucket from the terminated EC2 instances?Read More →

A company has a multi-tier web application that runs on a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB).The instances are in an Auto Scaling group.The ALB and the Auto Scaling group are replicated in a backup AWS Region.The minimum value and the maximum value for the Auto Scaling group are set to zero.An Amazon RDS Multi-AZ DB instance stores the application’s data.The DB instance has a read replica in the backup Region.The application presents an endpoint to end users by using an Amazon Route 53 record.The company needs to reduce its RTO to less than 15 minutes by giving the application the ability to automatically fail over to the backup Region.The company does not have a large enough budget for an active-active strategy.What should a solutions architect recommend to meet these requirements?Read More →
